1、2 in 1 Battery Charger: This for Ryobi P117 Dual Chemistry IntelliPort charger can not only power your for Ryobi 18V One+ batteries, but also charge your phones at the same time2、Dual USB Ports: It is especially upgraded with 2 USB ports that could quickly charge 2 USB devices simultaneously such as iPhone, iPad, Samsung, LG, Nexus, Android etc. Built in smart IC which will deliver the optimal current to your phones up to 3A max(two ports)3、Wide Compatibility: It charges all 12V-18V Lithium-ion/Ni-Cd/Ni-Mh batteries in one hour or less. For example: P104 P105 P102 P103 P107 P1084、Smart LED Indicator: The indicator lights let you know if the battery is charging, defective and too hot or cold to charge. Users can easily know if the battery is fully charged after using this intelligent charger5、Smart LED Indicator: The indicator lights let you know if the battery is charging, defective and too hot or cold to charge. Users can easily know if the battery is fully charged after using this intelligent charger

Features:It adopts high-precision ADC conversion, each step is 1mV, which can accurately judge the filling condition of nickel-hydrogen battery; realize battery voltage negative value-added (-deltaV) and zero value-added (0delta.V), accurately and reliably identify NiMH battery charging. Accurate voltage turn off the lithium battery charging. Multiple charge protection: battery over-voltage protection, over-current protection, pre-charge time protection, fast charge time protection, etc. It can automatically identify whether the connected battery is saturated. When loading a non-rechargeable dry battery or alkaline battery, the IC can recognize, stop the charging current and display the battery abnormal signal. Use constant current charging control, first pre-charge with a small current to wake up the battery that have not been used for too long and over-discharged, if the battery is found that can not be transferred to normal constant current charging in the preset pre-charge time (0.5H), it means the battery is abnormal, stop charging. When the battery is fully charged, it will be supplemented with trickle current to compensate for the natural discharge of the battery and the loss of power consumption of the line components until the power or battery is removed. When the lithium battery is intelligently shut down, there is no trickle current charging .
